Active clinical trials for "Fistula"

The surgical formation of an AVF offers a unique example of vascular remodelling and adaption. Yet, the specific factors which elicit remodelling events which determine successful maturation or failure have not been unambiguously determined. Computational fluid dynamic (CFD) simulations are increasingly been employed to investigate the interaction between local haemodynamics and remodelling and can potentially be used to assist in clinical risk assessment of maturation or failure. However, these simulations are inextricably linked to their prescribed boundary conditions and are reliant on in vivo measurements of flow and pressure to ensure their validity. This study will compare in vivo measurements of the pressure distribution across an AVF against a representative numerical model.

Objective: To assess the efficacy of the "connexion pancreatic duct to jejunum stented (CONDUCTJE-ST)" technique to prevent clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD). Summary Background Data: CR-POPF remains the most determining cause of morbidity and mortality after PD. The incidence of CR-POPF (grades B and C, ISGPS) is around 20% and is a potential source of severe secondary complications that are associated with a mortality of up to 40%. Methods: A prospective pilot study included 50 consecutive patients who underwent PD with the CONDUCTJE-ST technique, the steps of which are described, performed by the same surgical team from January 2018 to February 2020. No patient received prophylactic or therapeutic somatostatin or its analogues. The primary endpoint was the incidence of CR-POPF. Secondary endpoints were postoperative mortality and morbidity, hospital course and during the first year of follow-up. In a prospective study we have evaluated a "novel" technique, modification of the preexisting ones, for the reconstruction of the digestive continuity of the corporocaudal remnant in the PD, termed "connexion pancreatic duct to jejunum stented (CONDUCTJE-ST)", applicable to any type of pancreatic remnant, regardless of its texture and the diameter of the main pancreatic duct. The study was planned with the objective of achieving a significant reduction in the incidence of CR-POPF, so that CONDUCTJE-ST could be considered as a surgical procedure of choice in the management of the pancreatic remnant in PD.

In recent years, applications designed specifically to encourage physical activity in the field of mobile technology have gained momentum. As a result of the literature research, no examples of mobile health applications developed with educational content on fistula care, which hemodialysis-dependent patients can reach at any time and place, have not been found. Based on this, it was planned to increase the knowledge level of arteriovenous fistula care and examine their self-care behaviors and their adaptation to the disease with the mobile application developed with a focus on education on fistula care, which can be used independently by machine-dependent hemodialysis patients. In this context, it is aimed that dialysis patients will benefit especially in arteriovenous fistula care applications, thanks to the ever-increasing mobile applications in daily use with the developing technology. It is thought that the use of these technology-based trainings will be more comfortable, useful and encouraging for their own self-care. It is planned to be a guide for healthcare professionals.

The incidence of postoperative pancreatic fistula (POPF) after Distal pancreatectomy (DP) remains high. Of the available mitigation strategies, high-quality closure of the pancreatic stump is fundamental. Researchers failed to find a decrease in the incidence of POPF after stapler closure of the pancreatic stump compared with that related to hand-sewn suture in DP. Minimally invasive DP (MDP) is becoming the first choice for patients and surgeons, few studies have evaluated whether stapler closure is superior to hand-sewn suture for stump closure in MDP. Therefore, this retrospective study was aimed at evaluating the effect of stapler versus hand-sewn closure on the incidence of POPF after MDP.

Depression is a common psychiatric disorder in patients on maintenance hemodialysis (MHD). It may contribute to poor prognosis in a number of ways, including its effect on platelet function. We aimed to investigate the impact and underlying mechanisms of depression on the occurrence of cardio-cerebral vascular events (CCVE) and dysfunction of arteriovenous fistula (DAVF) in MHD patients. In this study, MHD patients were recruited and divided into depression and non-depression groups using the Hamilton Depression Scale (HAMD) in this prospective cohort study. Their clinical and laboratory indicators were collected and the occurrence of CCVE and DAVF were recorded through clinical follow-up, and analyzed, and the differences and possible influencing factors of CCVE and DAVF occurrence were assessed between the two groups of patients.

The goal of this study is to find the best techniques to take non-invasive images of the arteriovenous fistula (AVF) in hemodialysis patients.

This is an open follow-up clinical trials to evaluate a sustained efficacy and safety of Adipoplus inj. for 10 months (12 months after final dose injection)after Phase II clinical trial.

This study is a cross-sectional study of 110 Malawian women to compare the ultrasonographic and hormonal characteristics of women and without obstetric fistula. Hypothesis #1: Women with obstetric fistula have a mean cervical length measurement that is at least 10 mm shorter than the mean cervical length measurement of similar women without obstetric fistula. Hypothesis #2: Evaluation of the hormonal and ultrasonographic characteristics of women with obstetric fistula will allow us to assess the cause of amenorrhea in these women.

The purpose of this extension is to investigate and confirm the long-term (6 months) safety and efficacy of the preceding FATT-1 trial [ClinicalTrials.gov identifier: NTC00475410], which studied patients with perianal fistula treated having received adipose-derived adult stem cell (ASC)and/or fibrin glue.

Pancreatic fistula is one of the most serious complication after pancreatoduodenectomy. To reduce pancreatic fistula, many authors recommend pancreatic stent in pancreatojejunostomy. There are two distinct methods of pancreatic stent insertion: internal stent and external stent. There was few studies comparing these methods in preventing pancreatic fistula. Furthermore, its long-term effect was not known enough. The purpose of this study is to determine which is the best method in preventing pancreatic fistula and to investigate its long term clinical outcomes.
